Poe uses a lot of repetition in the Tell Tale Heart and he does this to emphasize the narrator’s feelings and thoughts. The narrator often says ‘very, very’ while he is recounting the events. This is to show how acute his senses are and how sensitive he is to everything around him. It also builds up suspense when he repeats himself as it show that he is getting more and more excited as he is failing to notice what he is saying showing that something is going to happen. The ‘evil eye’ was a motif of the story that angered the narrator. He became paranoid because of his fixation to it. Poe used this repetition of the eye to show us how mentally unstable the narrator is to feel so paranoid about something like an eye and also to show his obsession and over acuteness to the eye. This helps build up suspense as we are unsure of why the eye is so unnerving to the narrator and also makes us wonder what is going to happen next to the eye.
